18 Claims. (Cl. 45-82) This invention relates generally to a book hanger and more particularly to a book hanger for paper bound books such as telephone directories.

The mounting of books, particularly paper back books in such a manner that they cannot be damaged and so that they will still be readily accessible, has always been and continues to pose a problem. For example, the mounting of telephone directories which are generally large paper bound books is a particularly difficult problem. Directories are relatively expensive and, therefore, it is important to mount them in such a manner that they are not readily damaged. The problem of mounting telephone directories is further compounded by the fact that many times several directories are required at the same location. Racks or hangers heretofore provided have not been satisfactory. They have not permitted easy access to the directories. In addition, they normally have a limited capacity and do not prevent damage to the directories.

In general, it is an object of the present invention to provide a book or directory hanger which overcomes the above named disadvantages.

Another object of the invention is to provide a book or directory hanger of the above character in which the books or directories are readily accessible.

Another object of the invention is to provide a book hanger of the above character in which all of the information on each page of the book or directory can be easily read.

In general, the present invention utilizes a cylindrical member which is mounted on a rod for movement axially of the rod and rotatably on the rod. Means is provided for securing leaf-like elements to the cylindrical member so that one edge of each of the leaf-like members substantially abuts the outer surface of the cylindrical member and extends outwardly away from the cylindrical member. Such means consists of rod-like members which have one of their ends detachably secured to one end of the cylindrical member for pivotal movement of the rod-like members to permit their insertion between the leaves of a book. The other ends of the rod-like members are releasably retained by a cap which is rotatably mounted on the other end of the cylindrical member. The cap is provided with a slot through which the rodlike members may be moved into openings provided in the cylindrical member adjacent the cap and held therein after the cap has been rotated so that the rod-like members lie in a plane which is parallel to the axis of the cylindrical member.

The embodiment of my invention shown in Figures 1 to 7 of the dravn'ng consists of a member 11 of suitable material such as aluminum. The member 11 is preferably cylindrical, however, as is readily apparent, it may be hexagonal, or octagonal or any other shape desired as long as the shape defines a closed surface. Suitable means 12 is provided for mounting the cylindrical member '11, so that the cylindrical member '11 can be rotated about its longitudinal axis and also so that it can be moved longitudinally of its longitudinal axis. Such means, as shown, can consist of a rod 13 of suitable material such as steel which is afiixed to a base plate 14. .The base plate 14 is adapted to be secured to a Wall 16 l 3 or other suitable supporting surface by means of bolts 17.

The cylindrical member 11 consists of a hollow openended cylinder 18 which has mounted therein a pair of collars 19 and 21. Collar 19 is mounted on one end of the cylinder 18 and'the other collar 21 is mounted in the cylinder 18 approximately mid-way between the ends of the cylinder. Both of the collars are provided with flanges 22 which provide bearing surfaces which rotatably engage the rod 13. An insert 23 is provided in the other end of the cylinder -18 and serves to reinforce the end of the cylinder. Means 27 is provided for securing books or directories to the cylindrical member 11 and consists of at least one and generally several rod-like elements 28 which are releasably secured to the cylindrical member 11 and generally lie in a plane which is parallel to the plane of the longitudinal axis of the cylindrical member 11. One end of each of the elements 28 is provided with an L-shaped portion 28a which is adapted to be inserted into and removed from holes 29 provided on one end of the cylindrical member 11 and which extend through the collar 19. One leg of the L-shaped portion 28a extends in a direction which is at right angles to the longitudinal axis of the main portion of the rodlike element, and another leg of the L-shaped portion extends in the same direction as the main portion of the rod-like element. The other end of each of the rod-like elements 28 is provided with a portion 280 which extends at right angles to the main portion 28b of the rod-like element. The portions 280 extend into holes 31 provided in the other end of the cylindrical member 1'1 and through the insert 23.

Any desired number of rod-like elements 28 may be mounted on the cylindrical member '11. For example, as shown, two of the rod-like elements have been mounted on the cylindrical member 11 shown in Figures 1 through 6. Means 32 is provided for retaining the ends 280 of the rod-like elements 28 in the openings 31 and consist of a cap 33 which is adapted to fit over the outer end of the cylindrical member '11. The cap 33 is secured to the cylindrical member 11 by a screw 34 which is threadably mounted in the insert 23. The screw 34 extends through a dish-shaped handle 36 which engages the outer side of the cap 33. The screw, as it is tightened, urges the cap into engagement with the outer end of the cylindrical member 11. The cap 33 is provided with a flange 38 which is generally coaxial with the cylindrical member 11. The cap 33 is of such a diameter and the flange 38 is of such a length that the flange 38 extends over the portions 280 of the rod-like elements 28 to hold them in place as shown particularly in Figure 2. The cap is formed with a slot 39 in the flange 38 through which the ends 28c of the rod-like elements 28 may be inserted and removed as hereinbefore described.

In certain situations where only a few books are mounted on the book hanger, it is desirable to provide stop means 42 to limit the rotational movement of the cylindrical member 11. Such stop means consists of a stop member 43 which as shown is substantially V- shaped and is aflixed to the base plate 14 by suitable means such as bolts 44. The stop member 43 lies generally in the same plane as the axis of the cylindrical member and extends in the same direction as the cylindrical member. A pair of members 46 are mounted in two of the adjacent openings or holes 29. The members 46 are formed with a straight portion 46a which extends out radially from the holes 29 for a suificient distance that they will engage the stop member 43 for a purpose hereinafter described. The members 46 are also provided with an arcuate portion 46b which is normally retained within the collar member 19 by the cooperation of the collar member 19 with the rod 13. r

A pin 24 is slidably mounted in the rod 13 at right angles to the axis of the rod and has a length which is substantially greater than the diameter of the rod but which is slightly less than the inner diameter of the cylthrough one of the holes 31.

4 inder 18 as shown particularly in Figure 5. The pin 24 in cooperation with the collars 19 and 21 serves to limit the innermost and outermost positions of the cylindrical member lrl as hereinafter described. The pin 24 can be inserted and removed through the hole 26 which is provided in the cylinder 18 between the collars 19 and 21.

Use of my book or directory hanger may now be briefly described as follows: Let it be assumed that the book or directory hanger is in the out-of-therway position as shown in Figure 1; that is, the collar 21 is in engagement with the pin 24 and the inner portion of the cylindrical member 11 is adjacent the base plate 14. The book or directory hanger may then be moved to the in-use position from the out-of-the-way position by grasping the handle 36 and pulling the cylindrical member 11 outwardly until the collar 19 engages the pin 24.

After the book or directory hanger has been moved to the in-use position, books, catalogs, telephone directories or the like may be mounted on the same. For example, a telephone directory can be mounted on the cylindrical member 11 as shown in Figure 6. This is done by loosening the screw 34 so that the cap 33 can be turned to a position in which the slot 39 overlies one of the rod-like elements 28. The end 28c of the rod-like element may then be lifted upwardly and the rod-like element pivoted about its other end. Such a lifting movement is permitted by the loose fitting connection that the portion 28a makes with the opening 29. If desired, the rod-like element 28 can be completely removed from the hole 29 merely by lifting the same to an almost vertical position and then lifting it out of the opening. Normally this is not necessary or desirable when placing a directory on a hanger.

After the rod-like element has been lifted, the directory is opened to the desired place and then the directory is slipped in the open position under the rod-like element 28 so that its back faces the cylindrical member 11 and rests on the cylindrical member 1 1. The rod-like element 28 may then be lowered onto the open book and through the slot 39 so that the portion 28c extends After this has been completed, the cap 33 may be rotated to a position so that the next rod-like element can be removed and placed between pages of the book as hereinbefore described if additional rod-like elements are utilized.

The number of rodlike elements usedfor securing a directory or book to the cylindrical member 11 is primarily determined by the thickness of the book. For example, for a directory of the thickness shown in Figure 6, two of the rod-like elements are utilized. It is readily apparent that if the directory is of a greater thickness or if it is desired to hang more than one directory from the hanger, additional rod-like elements may be provided for this purpose.

After the directory has been mounted on the hanger, the cap 33 is rotated into a position so that, the slot 39 underlies the cylindrical member 11 after which the screw 34 is tightened so that the cap 33 cannot be rotated. With the slot 39 underlying the cylindrical member 11, the slot will normally be concealed from view and for that reason it will not be apparent to any one who casually views the racks as to how the rod-like elements are mounted on the cylindrical member. This is particular ly advantageous where telephone directories and the like are utilized in public places. This helps to prevent theft of the directory from the hanger. The screw 34 is of a type such as an Allen head screw which normally must be removed with a special tool. Since the screw is used for attaching the handle 36, it is not readily apparent to anyone casually observing the hanger that the screw must be loosened before the cap 33 can be rotated. This feature also helps to prevent theft of books or directories from the hanger.

After the directories have been mounted on the hanger,

the hanger may be moved between the in-use and outof-the-way positions shown in Figures 1 and 2. Since the weight of the directory or book would normally cause the cylindrical member to rotate about the rod 13 so that the book or directory 51 would underlie the directory hanger, the stop means 42 has been provided. The stop means as shown particularly in Figure 6 only permits limited rotation of the cylindrical member 11 the amount of movement being determined by the spacing between the members 46. The stop means thus maintains the directory in a position in which it can be readily used. It also ensures that once the directory has been opened to a desired location the directory will remain open in this location without holding it in this position. For example, it is readily apparent that when the directory is opened to the position shown in Figure 6, that the directory will remain open in this position without being held. It will also be noted that the directory is opened widely and that all the information contained in the book or directory 51 can be easily read, even the innermost portions. This is because the rod-like elements 28 take up very little space and permit complete opening of the directory or book to the desired location.

My book or directory hanger is particularly adapted for use in telephone booths as shown particularly in Figure 7. As shown therein, the hanger has been mounted on a base plate 14 below a shelf 53 provided in the telephone booth. A conventional coin operated telephone 54 is mounted above the shelf in a manner well known to those skilled in the art. It is apparent that when the hanger is in the in-use position shown in Figure 7 the directory on the hanger can be readily used by the person who wishes to utilize the telephone. The cylindrical member 11 is in such a position that its innermost edge is out beyond the front edge of the shelf 53 so that the pages of the directory can be readily turned. The directory when opened, will immediately underlie the area in front of the telephone 54 so that the directory can be viewed while using the telephone.

When the user has completed the use of the directory, the directory hanger can be moved to the out-of-the-Way position by grasping the handle 36 and pushing the cylindrical member 11 with the directories attached thereto into the out-of-the-way position underlying the shelf 53.

Movement of the directory hanger to the out-of-the- Way position facilitates movement within the telephone booth and also facilitates opening of the hinged door 56 in the telephone booth.

It is also apparent that in addition to being particularly adaptable for use in telephone booths, my directory hanger can also be utilized outside of the telephone booths by mounting the same on the wall or by mounting it in stands which are independently supported. When mounted in stands, the cylindrical member 11 may be mounted in such a manner that there is no provision for movement longitudinally of its axis.

In addition to being particularly adaptable for mounting books, directories and the like, it is readily apparent that such a hanger can also be used for mounting a plurality of samples, as for example, samples of rugs, draperies, upholstering material and the like.

Another embodiment of my invention is shown in Figure 8. In this embodiment, the cylindrical member 61 is of a larger diameter than the cylindrical member 11. Instead of only two rod-like elements 28, a plurality of the rod-like elements 28 have been provided around the entire periphery of the cylindrical member 61. The cylindrical member or drum 61 has been completely filled with a plurality of directories 62 in the manner shown. Since the cylindrical member 61 has been completely filled with directories, it is not necessary to provide stop means 42. The directories tend to counterbalance each other, and for that reason, the drum 61 will remain in any position to which it is moved.

For example, when one of the directories is opened as shown in Figure 8, the directory will remain in the desired open position without holding the directory. It is obvious that this will occur because the weight is equally distributed on both sides of the cylindrical member 61.

It is readily apparent that by utilizing cylindrical members or drums of various sizes that greater or larger amounts of books or directories or the like can be carried by the drum. By way of example, it has been found that a cylindrical member or drum 1% inches in diameter will carry 3,880 pages of telephone directories, that a 2% inch cylindrical member or drum will carry 6,280 pages of telephone directories and that a cylindrical member or drum 3% inches in diameter will carry 8,880 pages of telephone directories.

It is therefore apparent that large quantities of telephone directories can be carried on cylindrical members or drums of relatively modest diameters. This is particularly advantageous in large metropolitan areas where large numbers of telephone books are required for telephone booth installation.

Another embodiment of my invention is shown in Figure 9 and is particularly adapted for use with small telephone directories. It is substantially identical to the hanger shown in Figures 1 to 6 except that the cylindrical member is provided with a rectangular recess or groove extending longitudinally of the cylindrical member. Such a cylindrical member is particularly adapted for use with small books or directories because the sidewalls forming the recess 71 prevents the books or directories from being slipped out from under the rod-like element 28. This is particularly true where the directory is shorter than the length of the cylindrical member 11.

Another embodiment of my invention is shown in Figures 10, 11 and 12 of the specification, and consists of a cylindrical member 76 which is mounted on the means 12. The means 12 and the stop means 42 is identical to that hereinbefore described and hence will not be described in detail. The primary difference in this embodiment of the invention resides in the construction of the cylindrical member 76 as hereinafter explained. V

The cylindrical member 76 consists of a hollow open endedcylinder 77 in which are mounted a pair of collars 78 and 79. The collars 78 and 79 are fastened to a pipe 81 which has its outer ends crimped over the collars as shown. The pipe 81 is of such a diameter that it loosely fits on the rod 13. It is preferably formed of a suitable non-corrosive material such as aluminum which will slide readily on the steel rod 13. The collar 79 is afl'ixed to the cylinder 77 by a suitable means such as spot welding. The other collar 78 need not be secured to the cylinder 77 but if desired, it also may be spot welded to the cylinder. A snap ring 82 is mounted on the rod 13 and serves to hold the cylindrical member 76 on the rod 13. An annular ring 83 is aflixed to the pipe 81 by suitable means such as a press fit and has threaded therein removable studs 84 and 85 which protrude outwardly from the cylinder 77 and are adapted to engage the stop member 43 as the cylindrical member 76 is rotated.

Each end of the cylinder 77 is provided with notches 86 which are spaced equally about the circumference of the cylinder 77. At least one rod-like element 87 is mounted on the cylinder 77 and extends longitudinally of the cylinder 77. One end of the rod-like element is provided with a U-shaped portion 87:: which has its free end extending into one of the spaced openings 88 in the collar 79. The rod-like element 87 at the other end is provided with a portion 87 b which extends substantially at right angles to the main portion of the rod-like element and is provided with an additional portion 87c which extends inwardly from the portion 87b. It will be noted that this end of the rod-like element is adapted to be forced into the notches or slots 86 by snapping it 7 into place. 'An insert 88 is mounted in the forward end of the cylinder 77 and is fastened to the forward end by suitable means such as screws 89. The insert 88 is provided with a reinforcing piece 90 into which a screw 91 is threaded. The screw 91 serves to retain a cap 92.

The cap 92 serves a dual purpose. First, it serves as 'a handle for moving the cylindrical member 76 inwardly and outwardly on the rod 13 and second, it serves as a means for retaining the rod-like members 87 in the desired position. To that end, the cap 92 is provided with a flange-like portion 92a which extends in a direction coaxial with the cylinder 77. The flange-like portion 92a overlies the end 87b of the rod-like elements 87 and serves to hold them in. place. The cap is provided with an outwardly swedged portion 92b which facilitates gripping of the handle and movement of the cylindrical member between in-use and out-of-the-way positions. The

cap is also provided with a slot 94 to permit insertion and removal of the rod-like elements in a manner similar to that hereinbefore described.

To particularly adapt the hanger for use with small books andthe like, I have mounted on the cylinder 77 a U-shaped channel member 96 which is held in place by one of the rod-like elements 87 as shown. The U- shaped channel member is provided with a slot 97 which is adapted to overlie one of the slots 86 and to permit the rod-like element 87 to be inserted in one of the holes 88 in the insert 79.

The operation of this embodiment of my invention is very similar to that hereinbefore described. The changes incorporated in this embodiment are made primarily for the purpose of strengthening the device and to prevent tampering. For example, when it is desired to hang or mount small books in the hanger, the U-shaped channel member 96 prevents unauthorized removal of the book. When such a book is placed in the hanger, it is mounted with its back down in the U-shaped channel and then fastened in the channel by the rod-like element 87. The upstanding side walls of the U-shaped channel prevents the unauthorized removal of the book by preventing any attempt to slide the book out from under the rod-like element 87.

If additional small books are to be mounted on the hanger, it is readily apparent that additional rod-like elements and U-shaped channel members 96 can be provided on the cylindrical member.

The construction of the cap 92 is such that it can be screwed up tightly against the cylinder 77 so that the cap actually engages the end of the cylinder. 7 It has been found that the slotted portion actually engages the cap and prevents anyone from rotating the cap unless they have means for loosening the screw 91... In this way, the cap cannot be rotated to permit unauthorized removal of the rod-like elements 87 and the books held thereby unless the special tool required for loosening the screw 91 is used. The cylindrical member 76 can be removed from the rod 13 by removing the insert 88 and the snap ring 82.

Another embodiment of the invention is shown in Figure 13 in which a plurality of rod-like elements 87 are pletely filled with books.

Another embodiment of. my invention is shown in Figure l4. whichis similar to that shown in Figure with the exception that the cap 92.is replaced by a cap 101. The cap 101' is formed with a flat surface 102 which is adapted to abut. the front edges of the cylinder 77. As will be noted, the cap is provided with an outwardly flared portion 103 which facilitates grasping ofthe cap when his used as a handle.

The operation of this embodiment of my invention is very similar to the embodiments hereinbefore described with the exception that the rod-like elements 87 can be put'in placeand removed without rotation of the cap 101. With the embodiment shown in Figure 14 it has been found that the end portions 87b are firmly retained in place by the cap 101 when it is held tightly in engagement with the end of the cylinder 77 by the screw 91. Since the end portions 870 are curved as shown, these end portions cannot be removed from the slots 86 until the cap 101 is loosened by loosening of the screw 91. It has been found that this construction greatly facilitates the insertion and removal of telephone directories because it is not necessary to rotate a cap with a groove therein to the proper position before one of the rod-like elements 87 can be inserted or removed. The cap 101, however, still serves to inhibit unauthorized removal of the telephone directories.

Another embodiment of my invention is shown in Figure 15 which is also similar to that shown in Figure 10 with the exception that the rod-like elements are attached to the right hand end of the cylinder 77 as shown particularly in Figure 15. The rod-like elements 106 in this embodiment are provided with looped ends 106a which extend through openings 107 in the cylinder 77. An end cap 108 is provided for reinforcing purposes.

It is apparent from this embodiment of my invention that by mounting the rod-like elements 106 in this manner, the rod-like elements cannot fall from the cylinder while changing directories. In addition, the looped ends 106a permit the rod-like elements to be swung away from the cylinder to permit easy removal and insertion of directories.

My directory hanger has also been found to be particularly advantageous for use with telephone books because it always maintains the telephone books in such positions that the pages do not readily become crimped, folded or torn. My directory hanger also eliminates the need for hard back covers for the telephone directories. Because of its construction, it discourages theft of the telephone directories. The hanger itself is constructed in such a manner that it cannot be broken off or easily removed from the telephone booth or any other location in which it is installed.

It is apparent from the foregoing that I have provided a new and improved type of book or directory hanger which is particularly adapted for use in telephone booths, stands and the like. Its construction is such that it is economical to manufacture. It is relatively small and compact and can be moved to an out-of-the-way position. Its appearance is such that it blends into its surroundings and does not detract from the appearance of the structure with which it is used.
